VEH lCLE-AXLE.

SPECIPICA'I'ION forming part of Letters Patent No. 368,992, dated Aigst30, 1887.

Application filed May 20, 1887.

To cZZ whom 'it may concen:

Be it known that I, CHRrsToPHER G. BRAU- LEY, of Syracuse, county ofOnond'aga, in the State of New York', a citizen of the United States,have invented certain new and useful Improvementspin Vehicle-Axles, ofwhich the following is a specification, reference being had to theaeeompanying drawi ngs, in which- Figure 1 is a top plan view of one endof the-axle. Fig. 2 is a side elevation of a portion of the same,together with transv'erse sections on thev lines x y z.

My invention relates to the construction of the axle for wheeledvehicles, andV my object is to improve the strength and ntility; and itconsists in increasing the st'ength at the pointssubject to the greateststrain,:is follows: first, in inserting a fillet into one or all of thebends 0r angles, creating the crank in what is cornnonly known as acrank-axle,77 which fillet is either integral With the axle or rigidlysecured thereto; second, in enlargingthe size of the central portion ofthe axle between the crank-arms by a gradual taper from a point adjaccntto each crank-arm inwardly to a J point adjacent to the center of theaitle;

third, in constructing the crank -bends and that part of the axlebetween them of an oval or ovoid form in eross-seetion,the ovoiditybeing Vertical.

A is the axle,comprising the axle-shanks 1, provided with the spindles 2at their outer ends, and at their inner ends With the arms 3,

connecting or uniting the shanks to the body 4 of the axle 1, suchvConnecting-points constituting the crank-b'ends 5 and 6.

In the angle or bend 5, I place the fillet 7 extending outward along theunder side of the Serial No. 238.845. (No model.)

shank, and also downward along the arm 3, as far as may be desired ineither directon, and

either integral with the shank and arm or rigpoint adjacent to thecenter, the taper beinggradual. -This construction gives me anadditional vweight of metal to carry the center bearing strain,stiffening the central portion of the axle, so that the crank-armscannot be drawn inwardly by the strain of the load upon the Springs, andthus increasing the carrying capacity.

' What I claim as my invention, and desire to secure by Letters Patent,is-

1. A crank-axle eonstructed with a fillet in the bend or angle betweenthe crank-arm and the shank, substantially as described, for thepurposes set forth.

2. A crank axle vconsisting of shanks 1, spindles 2, arms 3, and body 4,enlarging centrally, and angle-fillets 7, substantially as described.

In Witness whereof 'I have hereunto set 1n y hand this 12th day of Maey,1887.
